HOST
I didn't meet Pin personally but she is a kind person and gave us detailed information to reach the place as the taxi driver somehow couldn't find it (and it's actually very easy to get to).
APARTMENT
The apartment is pretty small but alright. It has a good position - I would recommend to move around Bangkok by train or by boat (Ramnueng Pier or Ramkhahaeng). The kitchen is furnished with all you need to cook yourself (apart from the food of course), in the bedroom you'll also find a hairdryer and some other e-devices.
WI-FI
In both our mobile phones the WiFi wasn't working at all in the evening, reason why I couldn't write Pim about another problematic we had. Anyhow it works in the morning, but as in those three days we had to go away very early in the morning, we couldn't use it but on the first day.
CLEANLINESS
Something that bothered us was that the housekeeper only changed the duvet and not the bed sheet - I only noticed it when I went sleeping - and it had a strong sweat-smell. I looked for another sheet in the closet and the only one I found was smelling fine, however it had a quite big yellowish stain. If you're staying there, contact the host to know if clean bed linen are available or just get them yourself.
The towels I found had already been used and hadn't been changed as well, we had fortunately brought ours.
All in all it was okeish I'd say, it could have been better anyway.
